Foil vs Snyk Code.
Snyk Code's default SaaS deployment sends your code to Snyk's cloud for DeepCode AI analysis. Foil takes a different approach — the AI model itself runs on your Apple Silicon GPU, so your source code never leaves your machine.

| Feature | Foil | Snyk Code |
|---|---|---|
| Analysis method | On-device LLM (semantic reasoning) | DeepCode AI — hybrid symbolic + ML, run in Snyk cloud |
| Code leaves your machine | Never | Yes by default (SaaS)¹ |
| Logic-level vulnerability detection | Yes — auth bypasses, IDOR, race conditions | Yes — interprocedural dataflow and taint analysis |
| Fix generation | Deep Dive & Deep Scan rewrite code with explanation | DeepCode AI Fix suggestions |
| Internet required for scanning | No — fully offline | Yes — default SaaS deployment |
| Languages | 7 (Python, JS, TS, Go, Java, Ruby, C#) | 14+ languages |
| IDE integration | VS Code (coming soon) | VS Code, IntelliJ, and more |
| Dependency scanning | Code only | Yes — SCA, containers, IaC |
| Pricing | Free Community / €19 per user / mo Developer | Free (limited) / Team $25/contributing-dev/mo (5-dev min, 10-dev cap) |
| Runs on | macOS (Apple Silicon) | Cloud (SaaS)¹ |
1Snyk previously offered a Snyk Code Local Engine that scanned on-prem (results still uploaded to Snyk). It is deprecated and slated for removal in a future release. Claims above reflect Snyk's supported default deployment.
When to choose Foil
- + Your code cannot be sent to external servers (regulatory, compliance, IP)
- + You want fully offline scanning — no internet dependency
- + You want AI-generated code rewrites, not just fix descriptions
- + You want a flat, predictable per-developer price — no enterprise contracts or seat minimums
When to choose Snyk
- + You need an all-in-one platform (SAST + SCA + containers + IaC)
- + You need support for 10+ languages
- + You want native IDE integrations
- + Your team works on Linux/Windows (Foil requires macOS Apple Silicon)
